The traditional method of controlling street lamp lighting could not adjust the brightness of bulbs, while the management and maintenance had to rely on labour patrol. The combined ZigBee and GPRS technology with LED lights is an advanced controlling method for street lighting, particularly resolves the issues in monitoring and energy consumption. This paper presents a general system that incor...

Recently occupancy-based lighting control has shown a great promise towards achieving better energy efficiency. Generally, traditional systems use additional sensors to detect user presence with higher precision to better the control algorithms. In this work, we show how a smartphone-based indoor localization can be utilized for this purpose without deploying additional sensors. Apart from auto...

Currently wireless based control systems lack appropriate development methodologies and tools, indeed the control model and its underlying wireless network are developed separately which often lead to unstable and suboptimal implementations. In this paper we introduce a hybrid-based design methodology that considers Wireless Sensors and Actuators Network (WSAN) performance parameters in order t...
